If the dictionary is made of random words, cracklib-check in many cases doesn't recognize more than half of the input words: for i in `seq 1 34`; do echo -n > wordlist for j in `seq 1 20`; do tr -cd '[:alpha:]' < /dev/urandom | dd bs=1 count=$i 2>/dev/null >> wordlist echo >> wordlist done create-cracklib-dict wordlist > /dev/null cracklib-check < wordlist | grep ': OK' | wc -l done Actual results: 0 0 0 0 0 11 12 14 12 12 9 12 11 14 11 9 17 14 10 13 10 12 11 12 16 11 8 16 11 11 10 7 7 20 Expected results: all 0 Words with punctuation are now ignored: cracklib-2.9.0-5.el7.x86_64

cracklib-format script as called by create-cracklib-dict. The punctuation is removed from the created dictionary, but we do not ignore all punctuation now when checking for the dictionary match. (bug 985378) I'll change the cracklib-format script and eagerly await what regresses next. :) yes, I meant ignored by create-cracklib-dict, not by cracklib-check This request was resolved in Red Hat Enterprise Linux 7.0.
